Hot Rod & Classic Car 20W-50 Motor Oil

Lucas Hot Rod & Classic Car Motor Oil SAE 20W-50 is manufactured with the highest quality paraffinic base oils and is fortified with a unique additive package containing high levels of zinc, molybdenum and phosphorus, which provides a tougher, thicker additive film for maximum protection even under the most severe conditions. It lowers oil temperatures, extends oil life and minimizes metal fatigue. It improves the film strength between the cylinder wall and piston rings and slows oil burning and improves pressure in worn engines. It has good cold temperature properties and stands up to high operating temperatures. It is compatible with methanol and all racing fuels, as well as with synthetic and non-synthetic oils.

Lucas Hot Rod & Classic Car Motor Oil SAE 20W-50 is for muscle, showroom, classic and trophy cars without catalytic converters. It can be used in racing applications. Not recommended for passenger car use.

Available in convenient 5 quart bottles, the formulation is perfect for the Hot Rod and Classic Car crowd with an increased zinc value of 2100 PPM. Because many of these very special machines often spend long periods (winter for example in some parts of the country) off the roads, a number of the components of the additive package used in Lucas' Marine oils to provide rust and corrosion protection have been included in its unique formula.

Jim Scogin uses Lucas Heavy Duty Oil Stabilizer in his 1996 Tucker Sno-Cat

We used Lucas HD Oil Stabilizer in our engine (Chrysler 360) and Transfer Case for added protection, as well as Lucas HD 80/90 Gear Oil in the axles (Dana 60).

We installed a set of Richmond Gears PowerTrax (No-Slip) Traction System in the front and rear axles. Richmond Gears and I were worried that the system would not UNLOCK during turns and cause binding on the driveline due to the SLOW speeds in which the Sno-Cat operate. During the installation of the Richmond PowerTrax lockers I used Red "N" Tacky for the grease lubricant around the springs and between the locking gears. Finished off by filling the axles with Lucas HD 80/90 Gear Oil. The Richmond PowerTrax Traction Systems worked flawlessly along with the protection from the Lucas HD 80/90 Gear Oil. I only say this because when we took off the differential cover to drain the gear oil this summer and there was very little presence of metal (residual from years past) in the bottom of the axle housing compared to the last few years of regular maintenance.

Another positive benefit form using Lucas products was the decrease of fuel consumption by a large percentage. We travel 30 miles round trip to a remote site to repair our radar. In years past the Tucker Sno-Cat would consume 40 to 45 gallons of fuel (tank capacity is 50 gallons) making that 30 mile round trip. This past winter (2005-2006) we made that trip out and back, twice in one day, on one tank of fuel and regular trips for the rest of the winter season averaged the same fuel consumption.

This summer, during our pre-season maintenance, we plan to use ONLY Lucas Oil products in the engine, fuel system, transmission, transfer case, axles, hydraulic system, and greasing of the track drive system wheels/bogies. To decrease the risk of mechanical failure by using Lucas Oil Products could be a life saver for me and my co-workers on top of a mountain at 10,000 to 11,000 feet altitude. I am a beleiver in Lucas Oil Products so much that I use them in my personal vehicles. My wifes van (92 Ford Aerostar) had a delay in shifting into reverse. I drained some transmission fluid out and poured in some Lucas Transmission Fix and within a few months the problem was gone. Also, poured in some Lucas HD Oil Stabilizer on the next oil change and it helped with the knocking noise coming from the engine just after startup. Great products! It has saved me alot of money! THANK YOU!
